Reaction of embelin(2,5-dihydroxy-3-undecyl-1,4-benzoquinone) with ethylenediamine in equimolar concentrations yields 1,2,3-trihydro-6-hydroxy-7-oxo-8-undecylquinoxaline (3), 2,3,4,7,8,9-hexahydro-5-undecylpyrazinoquinoxaline (4) and 5-(2,3,4,7,8,9-hexahydro-5-undecylpyrazinoquinoxalin-10-yl-1,2,3-trihydro-6-hydroxy-7-oxo-8-undecylquinoxaline (5).Their structures have been confirmed by IR, PMR and mass spectral data.Compound 5 shows significant antibacterial activity and slight hypotensive activity in preliminary pharmacological screening.
